Oak Creek Reservoir elevation, full record

14.5% full at the latest reading - across the storage record since May 1, 1953 it ranged from 0.9% (May 1, 1953) to 100.0% (July 12, 2019). Percent full is storage against the 39,210-acre-foot capacity basis, not a share of the elevation plotted above. Every percentage here is measured against today's capacity basis; a reservoir's surveyed capacity changes as sediment accumulates behind the dam, so early-record percentages are indicative rather than exact.
